Why are hip-hop vets able to fill arenas while many newer acts cannot?

If you look at the touring music industry, the acts that are filling big venues from from rock, pop, and country. Hip-hop artists in general don’t have this ability. Why?

B-Real of Cypress Hill has a theory. He writes:

“The big bro @FINALLEVEL made a huge point that HipHop veterans are filling seats and selling tix while some of these younger artists struggle w/ selling tix. We sell tickets because our fans bases are built upon hard copies sales of our music as oppose to having high steam numbers. Which are usually boosted thru click farms and when they use these click farms they forget that it’s bots and not actually people streaming their music. So when they see these outrageous stream numbers they think they got it poppin until they go on sale for a live show and you can’t fill not even a 3rd of the venue.”
